Title: Improvements in or relating to a method of knitting on circular knitting machines and to knitted fabric
IPC: D04B9/18
Filed: 1944-10-30
Abstract: 600,921. Knitting. HEMPHILL CO. Oct. 30, 1944, No. 21164. Convention date, Nov. 2, 1943. [Class 74(ii)] A fabric incorporating wrap loops (e.g. an article of knitted footwear) is made on a circular, independent needle knitting machine by a method including drawing the body yarn and (except in the case of single wall wraps) a wrap yarn over parts of the backs of radially motionless sinkers, these parts having all the same height, and through the needle loops of the previous course; casting off the previously formed needle loops by the throats of the sinkers acting only on the intervening sinker loops of that course; and causing the newly drawn sinker loops to pass from the backs to the throats of the sinkers over the tops of the nibs. A more symmetrical and betterlooking fabric is thus produced: Fig. 16 shows such a fabric. A second wrap yarn may be fed to obtain " colour within colour." Each sinker has a flat back 16, preferably slightly higher than the throat 17. The nib 18 is preferably somewhat thinner than usual, where it joins the sinker. A flopper cam 7, brought into action by a lever 10, moves the sinkers in sooner and further than would the normal cam 6: this causes the yarn to be laid, and the loops drawn and measured, over the backs 16 of the sinkers which are subsequently retracted by the centre sinker cam 14 to cause the newly drawn sinker loops to pass over the nibs 18 to the sinker throats 17. The slope 13 of cam 14 is preferably more abrupt than usual, to confine the resulting strain to comparatively few loops at a time. The wrap yarn 30 may be fed by a wrapping spindle or other suitable mechanism: it is preferably fed higher up the needles than the body yarn, to avoid its being pinched in the needle latches. Specification 3 0 0,6 0 5, [Class 74(ii)], is referred to.

Abstract: 322,158. Bayon, H. P., (Magnasco, Roggero & Co.). July 21, 1928. Compositions containing organic condensation products and cellulose materials.-Cellulosic material is modified by treatment with a solution of an oxidizing acid or acids such as an aqueous solution of nitric acid or of a mixture of nitric and sulphuric acids, and the modified material is incorporated with the initial condensation product of a phenol and an aldehyde, to form an amorphous mass which may be stored for an indefinite time. The mass may be subsequently pulverized and moulded into articles under pressure and heat. The initial condensation product may be formed in the mass itself or separately. A dichlorbenzene such as paradichlorbenzene may be introduced into the composition. Examples of suitable cellulose materials are wood pulp, sawdust, shavings. cotton linter, flock, and rags, paper cuttings, straw and artificial silk waste. In an example, 100 kgs. of wood-pulp cutting is reduced to a fine powder and treated for from 12 to 24 hours with a 5 per cent aqueous solution of equal parts of sulphuric and nitric acids. The soaked powder is strained and washed first in a weak alkaline solution and then in water. The resultant mass is dried and pulverized and steeped for six hours or more in its own weight of phenol. Formaldehyde and carbonate of soda are added and thoroughly mixed. Aqueous liquor is removed and the resulting mass is mixed with an alcoholic solution of paradichlorbenzene. The composition is then dried and milled to a powder. Pigments, ground glass, metal powders and other substances may be added to the moulding powder. Specification 298,793 is referred to.

Abstract: 1,183,885. Reforming hydrocarbons. MARATHON OIL CO. 6 May, 1968 [29 May, 1967], No. 21372/68. Heading C5E. A hydrocarbon conversion process for the simultaneous production of benzene and a substantially olefin-free gasoline blending stock from a gasoline produced by cracking of hydrocarbons and from a raffinate produced by extraction of a hydrocarbon stream from a catalytic reformer comprises the steps of (a) fractioning the gasoline-raffinate feed either singly or co-mingled to remove hydrocarbons containing seven or more carbon atoms as a bottoms product; (b) hydrogenating at least a portion of the overheads from the fractionation step under conditions sufficient to hydrogenate substantially all of the olefins contained therein; (c) catalytically isomerizing at least a portion of the effluent from the hydrogenation step so as to enhance the branching of the carbon chains of the molecules; (d) fractionating at least a portion of the isomerized stream so as to separate out an isomerate suitable for gasoline blending; (e) catalytically reforming a hydrocarbon stream to produce a reformate containing both aromatics and non- aromatics; (f) separating a major portion of the aromatics from at least a portion of the reformate stream so as to produce a predominantly paraffinic stream and a predominantly aromatic stream; and (g) combining at least a portion of the primarily paraffinic stream with the gasoline or the hydrogenated product prior to the isomerization step. The hydrocarbon stream which is catalytically reformed may comprise the bottoms from a distillation of the isomerate. Alternatively or additionally, it may comprise a normal reformer feed. The separation of aromatics from non-aromatics may be by solvent extraction. Where the sole feed to the reformer is the bottoms from the isomerization reaction, the aromatic fraction will comprise mainly benzene; where other reformer feeds are used, alkyl benzenes will also be included. The hydrogenation may be carried out over a sulphided nickel tungsten on alumina catalyst. The isomerization may take place over a heavily chlorided platinum on alumina catalyst. The reforming process is referred to as conventional.

IPC: G01V1/28
Filed: 1966-05-17
Abstract: 1,151,721. Seismic signal processing. MOBIL OIL CORP. 17 May, 1966, No. 21801/66. Heading H4D. A time-domain filter operator, for filtering seismic data and having an impulse response which is varied with time, is defined by assigning values of amplitude and polarity to each of a series of sampling intervals and either (a) varying the values while maintaining the sampling interval constant or (b) increasing equally each of the sampling intervals. As described, the operator is convolved with a seismic trace to enhance the primary signal-to-noise ratio, and allows for the frequency-selective filtering of the seismic signal by the earth. The earth can be considered to have an impulse response which varies as the seismic signal propagation time increases and requires a filter operator with an impulse response which broadens with time as shown by lines 13, 13a, 13b in Fig. 3A, 4A, 5A. In the Fig. 6 embodiment the time-domain filter comprises rotating magnetizable band 23 and, a head 22 for recording the seismic trace on the band, and a series (only four are shown) of replay heads 30-33 whose spacing defines the operator sampling intervals. Switches 34-37 and variable-gain amplifiers 38-41 determine the assigned amplitude and polarity values of the filter, and the amplifier outputs pass via summing circuit 50 to recorder 51 and a monitoring oscilloscope. A programmer 52 and mechanical linkage 55-57a are used to increase continuously the spacing between the replay heads and thus increase the sampling intervals with time, as indicated in Figs. 3A, 4A, 5A. Amplifiers 72-75, gain-controlled by programmer 52, compensate for increasing attenuation of seismic signals with propagation time. Instead of varying the sampling intervals, the assigned values of amplitude and polarity for fixed intervals may be varied with time (as indicated in Fig. 9) by a programming system (52a) (Fig. 8) including function generators (130-133) which control the multiplication factors of multipliers (100-103).

A snowless ski slope comprises a member having a ski contacting surface provided with means whereby it can be moved at predetermined speeds and in which the ski contacting surface is such that a ski may slide thereon whilst allowing the edge of the ski to sink therein. The snowless ski slope 10 pivots at the lower end which leads to a ramp 26 and pivotally connects with a platform 20 at its upper end. The platform is pivotally connected to a ground support by a beam 28 and the inclination of the slope is varied by a piston and cylinder 14. A variable speed motor 81 beneath the slope drives an endless belt conveyer. The surface of the belt may comprise looped nylon threads or short nylon filaments secured to a base which may be jute, three ply canvas or the like. A pad of resilient nylon may be inserted between the base and the pile. To adjust the tension in the belt, an end roller is mounted in a housing having a threaded sleeve movable along a screw. The belt may comprise a number of hinged sections, the edges being turned up by members with concave surfaces. The belt may have a snow bump of fibre glass sliced transversely into segments to pass round an end roller: the adjacent ramp having fingers spring urged to contact the belt and pressed back by the snow bump. A viewing mirror 30 mounted at the lower end of the run is adjustably inclined by a motor driving and drive rod 38. The ski surface may be circular and may be rotatably mounted within a platform, the inclination of which may be varied by screw jacks. The rotatable surface is mounted on rollers and rollers engage the periphery. The surface may have a central radial practice bar. The ski slope may have a practice bar which remains transverse to the slope only so long as pivoted lever arms on a rod within the bar are gripped and forces the end outwardly of the bar to engage the bracket. The belt may be marked out as a salome by pairs of spots to define gates and a source of light may reflect from a reflector on a skier's boot on to a photo-electric cell in circuit with a device to record the passage of the skier or electric feelers may be used and the spots may be pressure sensitive. A light source may be situated at the upper end and a photo-electric cell at the bottom to record the number of times the skier crosses the line. The ski may have a stepped undersurface centrally grooved and with reinforced nylon, bottom or edges. The ski pole may be formed of hollow tubing which may be fibreglass reinforced with an epoxy resin tapered to a smaller open end or the end may be rubber tipped. A number of ski runs may be assembled under a cover, side by side and back to back, with common ramps. The ski surfaces may be adjustable to give slopes in various directions and the belt may run laterally of the slope.

Classes 29 and 64(3) In a method of cooling hot liquids in containers such as bottles or jars, the containers are placed in a cooler which is continuously moved so that different parts of the containers are successfully turned towards a stream of ambient or refrigerated air directed on to the containers from above. The method is said to prevent the containers from experiencing a large thermal shock in that a cushion of air warmed by contact with the containers is formed thereabove and is continuously cooled by the cooling air. In an apparatus shown for carrying out the method the containers (not shown) are loaded into a generally horizontally extending frame 10, 11 supported on rollers 12 and rotated about its longitudinal axis by a motor 15. The frame also includes a loading conveyer 18 and a grille 19 for supporting the containers during rotation of the frame. A shroud 16 above the cooler contains three fans 17 blowing air over the containers in the frame. The sides of the apparatus may be formed by screens which permit air to enter at the bottom and escape from the region adjacent the shroud 16 and at the same time prevent the containers from being subjected to lateral air currents.
